光学湍流对激光的大气传输有着重要的影响,其中光强闪烁是湍流效应中最基本也是最重要的一个效应,一直是一个十分令人关注的问题.在处理激光在湍流大气中传输的光强闪烁效应时,认为光强闪烁是由大尺度光强起伏对小尺度光强起伏的调制,并对其调制过程进行了讨论.基于光强闪烁的调制理论,对近地面典型条件下激光大气传输的光强闪烁指数及其影响因素进行了分析.
Optical turbulence has an important influence on the atmospheric transmission of laser light, and the flicker of light intensity is the most fundamental and important effect of turbulence effect, which has always been a very interesting issue.In dealing with the intensity of laser light transmitted in turbulent atmosphere When the flickering effect is considered, the flickering of light intensity is considered as the modulation of small-scale light intensity fluctuation by the large-scale light intensity fluctuation, and the modulation process is discussed.According to the modulation theory of light intensity flicker, the laser atmospheric transmission under the typical ground conditions The index of light intensity flicker and its influencing factors were analyzed.
